Method and system for obtaining internet radio resources based on session initiation protocol

Abstract

A method for obtaining Internet radio resources based on Session Initiation Protocol (SIP) is adapted for use between an administrator server and at least one client terminal. The method includes the following steps: (a) enabling the client terminal and the administrator server to set up a tunnel based on the SIP; (b) enabling the client terminal to send a SIP message requesting radio station data to the administrator server through the tunnel; and (c) enabling the administrator server to provide the radio station data to the client terminal through the tunnel. Since SIP has very good flexibility and functionality, obtaining Internet radio resources based on the SIP can overcome inconveniences associated with searching by the user.
